Help adding images to thread

so I created a thread under the Runescape account rentals subforum but I'm having an issue when adding the link for the image. when I'm editing the thread the image appears as normal but when I'm not in the edit mode it it just says . Am I doing something wrong? Does it appear this way for other people? I'm using imageshack. Thanks for the help!

Here is the thread I'm referring to
Safe & Secure Rentals | Maxed Staker | No Deposit! | Cheapest Rates | Price Matching!

Edit:
Solved! I was using wrong link!
